Are you really sure that they provide a Dynamic DNS for free ? Their
free service just maps a free url (like "you.dyndns.org") to your IP.

If you want to update real DNS entries on your own domain (like
"you.com"), you have to pay for the extra "Custom DNS" service. $30 a
year or something.

Do someone know of a good real dynamic DNS update service (with your own
domain) ?
